For Seniors: Managing Power on a Windows 8.1 Laptop
One of the big differences between a desktop computer and your laptop is that your laptop can run off of a battery. Battery life, or the length of time it takes your laptop battery to run out of juice, is getting better all the time — some recent laptop batteries get as many as 9 hours on one charge.
A recent comparison by Laptop Magazine found very few models that stayed the course for as many as 20 hours. Consider avoiding laptops that get as little as a couple of hours of battery life.
For that reason, it’s important that you understand some tools that Windows 8.1 provides to help you manage your laptop power, including these:
Choosing a power plan, which has preset timings for actions such as dimming your screen or putting your computer to sleep.
Creating a customized power plan by choosing settings you want.
Adjusting settings for your display that deal with the screen brightness (a brighter screen uses more power), how frequently your screen automatically dims to save battery charge, and so on.
Changing how much time lapses before your laptop automatically goes to sleep — a state that uses minimal power but keeps the currently open documents and programs active (and quickly available to you).
Defining power button functionality gives you some control over what happens when you press the laptop’s power button or close the lid.
